The big story of this year's election campaign is big money. Since the Supreme Court, through its Citizens United ruling, has made it easier for corporations, unions and rich individuals to raise and spend unlimited amounts of money, Republicans have seized the advantage.
Right now, an analysis by NPR finds that Republican allied groups are outspending their Democratic counterparts by 8 to 1.
Democrats knew that they would be disadvantaged under the new campaign finance rules created by the Supreme Court. But the disparity between the amount of money Republicans can raise in unlimited anonymous donations and what the Democrats have been able to raise is huge.
Federal election law has required the public disclosure of campaign donors for nearly 40 years.
But this year, outside groups are playing a powerful role in the presidential election. And some of them disclose nothing about their donors. That's despite what the Supreme Court said in its controversial Citizens United ruling two years ago.
